Just go train dude. My solution to everything is Soto Makikomi to O soto gari or Uchi Mata to Tai otoshi. You'll come up with a solution depending on what you train.

i just looked them up and it was th "o soto gari" he showed me as a solution to this problem. also the uppercut idea is good but it looks a lot more violent to by standers and you "threw the first punch" whereas o soto garing someone and then doing standing silat/kali like arm bars or branch up branch down **** would look less violent?
